3,500 college students that america has failed them. >> in a single generation, we've fallen from first place to 12th place in college graduation rates for young adults. >> how did we get here? >> we got a little self-satisfied. and other countries have, i think, outworked us. they have out-invested. they have taken this more seriously. i think this is a wake-up call. >> reporter: mr. obama has set a daunting goal -- raise college graduation rates from today's 40% to 60% in 10 years. by adding at least 8 million graduates. >> the single most important thing we can do is to make sure we've got a world-class education system for everybody. >> reporter: some education experts say the problem isn't colleges, but high schools that fail to prepare students once they get there. >> large percentages show up needing some kind of remediation. in reading, in mathematics, in courses that colleges would like to think had been done at high schools.

>> reporter: to tackle that problem, the president is pushing a set of common academic standards so that all students would have the same skills. and the president wants to get more students in the door by making college more affordable, through increased financial aid and student loans. >> it took 30 years to get to number 12. do you think we can really get to number one in 10? >> i do. and is it an ambitious goal? absolutely. is it going to take hard work? absolutely. frankly, failure's not an option here. >> reporter: secretary duncan says everything is on the table. there's talk of adding more school days, hiring an army of new teachers, and of course, raising standards. none of that is cheap, and could be a tough sell for states with tight budgets. yunji de nies, abc news, the white house. >> and the president's goal is that everything will turn around by 2020. so he really is looking ahead. one of the things a lot of people are pointing to, rising costs. it costs a lot to go to college. >> a ton to go to college.

welcome back, everybody. scientists are wondering where so many of the world's frogs and toads have gone. now they're trying to do something about it. >> a two-month, four-continent study is getting under way to locate species on the brink of extinction. richard black of the bbc has details. >> reporter: in many parts of the world, the characteristic croaking has been suddenly stilled in recent years. amphibians are in serious trouble, with one-third of species at risk of extinction. >> extinct, extinct, extinct -- >> reporter: many have already apparently disappeared. over the next two months conservationists will mount a series of expeditions to see whether a few individuals may be hanging on. >> we've compiled a list of around 70 species that we know haven't been seen in the last decade. so this is a large, coordinated effort to basically go out and find or try and find a lot of

these species. >> reporter: the most iconic is the golden toad of costa rica. in 1979, it was thriving. a decade later, it had vanished. the biggest threat to amphibians is destruction of the places where they live. but in recent years, a lethal fungal disease has decimated frogs in many parts of the world. there's no way to stop it. the outlook for the world's amphibians is not good but it may look slightly better if the forthcoming expeditions do find any survivors from species missing, presumed extinct. richard black, bbc news. >> the sad reality is that we have some hand in why some of these species are getting extinct. there was a frog called the hula painted frog of israel, last seen in 1955. this is the biggest problem is we were draining all these bodies of water to make sure malaria wasn't brought about, that mosquitos weren't having a chance to linger, there went the frogs. >> trying to do one thing and

ended up doing something to the environment bad.

finally this half hour, here's something we don't talk about often here on "world news." and that is puberty. a new study says more and more girls are reaching it earlier and earlier. >> the reason for that remains unclear. but what is clear are the consequences for young women. here's dr. richard besser. >> reporter: parents are worried about a new study from pediatrics making headlines. >> we're just scared about it because we didn't know if this was something that was going to cause other problems years down the road. >> reporter: chanda lewis' anxiety seems to be supported by this study which suggests

american girls are entering puberty earlier than ever. if true, concerning news. >> girls at earlier onset of puberty are at risk or higher risk for earlier onset of sexual initiation and teenage pregnancy, as well as earlier onset of substance abuse. long-term these girls can be at higher risk for breast cancer and adult obesity. >> reporter: what does this study really say? we asked the senior author. many of the headlines about this study were the age of onset of puberty is going down dramatically. is that a fair conclusion from this study? >> i don't think from this study we can say that the age is going down in the world at large. >> reporter: so despite all the press reports, the girls in the study are not representative of the general population. and some cases were selected because they had existing risk factors for early puberty. >> this study was not actually designed to look at whether puberty was happening earlier or not. >> reporter: but the trend is going in the wrong direction. with many other studies indicating that girls do face puberty earlier.

researchers believe there are two key reasons. increased rates of obesity in children due to poor diet and declining physical activity and chemical and environmental factors. in fact, the authors are actually in the first year of a long-term study, trying to understand whether chemicals in the environment cause early puberty. >> we've done studies to show that heavier girls do have earlier onset of puberty. but the other issue that's of growing concern is chemicals that are found in everyday household products. >> reporter: critical information for parents hoping to protect their daughters. the ultimate goal of this study is to find preventible risk factors for early puberty. clearly, obesity falls into that category. dr. richard besser, abc news, new york. >> you have to imagine for so many parents out there, this is such an uncomfortable topic of conversation. to have to have it at 8 years old with your child? >> i can't imagine, yeah. the thing that's also scary, too it's all linked to obesity. pipio

the least and you'll get to see him on the journey which bill weir tagged along for. >> god bless bill. better him than us. >> yeah, exactly. good morning and thanks for being with us on this tuesday. i'm vinita nair. >> i'm rob nelson. a case of air rage has boiled over aboard a flight arriving at new york's jfk airport and now a flight attendant is in custody. >> wabc's jeff pegues reports on what led to the arrest. >> reporter: steven slater was smiling when police led him away in handcuffs. >> mr. slater, why are you smiling? >> reporter: this time there would be no quick escape, unlike what police say happened when the flight attendant bailed out of this jet blue plane on the jfk tarmac. >> kind of funny. >> reporter: his neighbors can't believe what police say he did. >> it's the most ridiculous thing i heard in my life. >> reporter: flight 1052 from pittsburgh was pulling into the gate. police say slater got into an argument with a passenger about luggage in an overhead compartment. investigators say a passenger yelled, cursed, and may have even hit slater, who then apparently snapped.

a passenger who says he was on the plane as well wrote that slater yelled "to the passenger who just call me a expletive, expletive you. i've been in this business 28 years and i've had it." >> it's a strange way to quit, put it that way. i don't think he'd be able to come back. >> reporter: according to police, slater then activated the emergency chute, jumped off the plane, headed to his jeep, and drove to his bell harbor home. >> you saw police pull up to the house? >> i did. >> reporter: where he was later arrested. he's been a flight attendant since 1994. he didn't start working for jet blue until two years ago. and after what police say happened on this jet blue flight, his future with the company is very much up in the air. >> he just made a bad choice there. lost his cool. >> reporter: the flight attendant, steven slater, is facing up to seven years behind bars if he's convicted on all of the charges that he's facing, and that includes reckless endangerment. by the way, authorities say that

he grabbed beer before he jumped from the plane. jeff pegues, abc news, new york. investigators in two states say they are trying to track down a serial killer. they say five men have been fatally stabbed in michigan. the suspect is described as a white male asking for directions or help with a vehicle. nearly all the victims were african-american. now police in leesburg, virginia, think three weekend attacks may be linked to the same suspect. a former b-2 stealth bomber engineer could face life in prison after being convicted of selling military secrets. a federal grand jury in hawaii found him guilty of helping china design a stealth cruise missile. he'll be sentenced in november. the case is among several involving allegations of chinese espionage in the u.s. lawmakers say they will fight budget cuts by the pentagon. defense secretary robert gates says he needs to do away with one of the country's major

latest display of palin power. sarah palin is lined up against the nra, backing her own candidate for governor, karen handel. >> are you ready to elect a pro-life, pro-second amendment, commonsense constitutional conservative who will fight like a mama grizzly for you? >> reporter: in connecticut, political smackdown. linda mcmahon, former ceo of world wrestling entertainment, is vying for the republican nod for senate. she's up against rob simmons. who lifted his campaign off the mat when questions swirled about how pro wrestling treated women -- >> bark like a dog! >> reporter: under the leadership of mcmahon and her husband vince. >> that was george stephanopoulos reporting. one other primary today, three minnesota democrats battling for a shot at becoming the party's first governor since 1986. house lawmakers are back on capitol hill this morning to debate and vote on a jobs bill. democrats say their $26 billion measure is aimed at saving hundreds of thousands of jobs for teachers along with state and local government workers. republicans oppose the bill.

they say it is too expensive and amounts to a preelection payoff to democrats' union allies. in medical news, there's a promising new test in the battle against alzheimer's. researchers from belgium discovered the test can detect the disease before symptoms even appear. the spinal fluid test measures certain proteins linked to the disease. researchers say the test was accurate almost 100% of the time. the push is on to convince americans that seafood caught in the gulf of mexico is safe to eat. federal health authorities insist all the samples of gulf seafood tested so far show no signs of contamination. but veteran gulf shrimpers do not agree. >> i don't believe them. we have oil right here. right here we have oil. and then they say it's safe to eat? i don't know, i don't believe i'll be eating it. maybe somebody else will. >> despite the government's claims that gulf seafood is safe to eat, many distributors say they will not send out their shrimp boats any time soon.

they say for now, customers just aren't buying. here's a look at your weather across the country. stormy from fargo to chicago with 70-mile-an-hour winds, hail, and a chance of tornados. scattered showers in new york and new england. drenching rain in florida stretching later into new orleans. another rainy day in the desert southwest. >> phoenix gets up to 107. albuquerque 92. boise 88. 90s from minneapolis to indianapolis. 88 in boston. 93 here in new york. and 96 in atlanta. miami will hit 88. and new orleans 95. now to my favorite story of the morning. they were a long way from the big easy but the saints came marching in. right through the doors of the white house. >> we're going to get you to do a who dat? >> who dat is? >> president obama played host to the new orleans saints yesterday to celebrate their 2009 super bowl victory. he praised the team for their accomplishments on and off the field, especially for their role

the run was recaptured monday near yellowstone park. clayton sandell has more. >> this morning, manhunt. >> breaking news in a massive manhunt tonight. >> they're considered armed and extremely dangerous. >> reporter: it's a manhunt in the most unlikely of places. >> an escaped killer is caught near yellowstone park, still on the run, a couple who think they're bonnie and clyde. >> reporter: among the waterfalls, wildlife, and summer tourists at yellowstone national park, officials here continued to search for fugitives connected to a tragic double murder. >> to put an end to this nightmare, basically a national nightmare. >> reporter: a break in the 10-day-old case, one of the men, tracy province, was captured near the park. >> at 6:20 this morning, tracy alan province was arrested by u.s. marshals. >> reporter: province had been spotted on sunday at a local church, singing along, unnoticed, with the choir. >> u.s. marshals last night set

up surveillance in the area of that church where he was observed. they immediately arrested him without incident. mr. province did have a 9 millimeter handgun in his possession at the time. we still have john mccluskey and miss welch still on the run. >> reporter: escapee john mccluskey is believed to be with casslyn welch. she's his first cousin and fiancee. the two remain at large. according to the police they should be considered armed and dangerous. >> mccluskey and his partner who helped break him out of jail consider themselves bonnie and clyde. they joke about it. think they've taken the personae that this is some type of a movie and this is some kind of a joke that they are living. but it is not. >> reporter: here in yellowstone the campers we talked to seemed to be taking all the excitement in stride. >> there's not much we could do. we could have packed and up gone home. but we're here until tomorrow. we've come from minnesota. >> reporter: the drama began

almost two weeks ago when three convicted felons -- province, mccluskey, and daniel renwick -- busted out of this phoenix, -kingman, arizona, prison. police say welch tossed the men wire cutters so they could slice through the fence. from there they hijacked a big rig at gunpoint, driving to flagstaff. they were later seen in phoenix. renwick, who eventually split from the group, was recaptured last weekend in colorado. the others remained on the loose. the search for the remaining trio gained urgency after linda and gary haas were found dead in new mexico, burned to death inside their camping trailer. the oklahoma couple was identified only after a rancher found their names and phone numbers on their dog's i.d. tags. their truck was found 100 miles away in albuquerque. police say evidence links the case to the inmates. mccluskey's own mother is now in custody. u.s. marshals arrested her on saturday for allegedly giving her son and niece money, clothing, food, and a getaway

car. >> john mccluskey, if you're out there watching, i just come back from payson jail, they got your mother locked up, she's in her little uniform, handcuffed. he'll never realize how bad he's hurt me and his mother. >> reporter: mccluskey, like province, is a member of the aryan brotherhood white supremacist group. investigators are now looking at his past, trying to anticipate his next move. >> the only way they're going to be able to keep going is to keep breaking the law, which is rob people, steal cars, break into stores, hold people up at gunpoint, and keep moving. >> reporter: the case has captured the nation's attention as the pursuit has spread across the west. >> cops also need you to look out for convicted killers and prison escapees tracy province and john mccluskey. >> reporter: as the manhunt continues, officials are being asked why hardened criminals were allowed to be at a medium-security prison in the first place.

mccluskey was serving time for the attempted murder of a police officer. and province for stabbing a tucson man over 51 times in 1993. >> we have violent offenders throughout the prison system in medium security. our prison system has 68% violent offenders throughout. >> reporter: officials say mccluskey and welch can't run forever. >> in my mind it's clearly only a matter of time. that they eventually will get caught, because they're leaving now a track record of a lot of -- like hansel and gretel, a lot of crumbs along the way. >> reporter: authorities now believe those crumbs may lead them out of yellowstone and one step closer to nabbing this modern-day bonnie and clyde. i'm clayton sandell in yellowstone national park, wyoming. >> scary story. >> it really is and the scariest thing is there's a $40,000 reward, which sounds enticing. but at this point, clayton kept referencing them as bonnie and clyde. the biggest fear is these two have nothing to lose.

there's fear if someone tries to approach them, they're very dangerous and this probably won't end in a calm manner at all. >> the park is crowded this time of year. just don't approach, don't detain, just relax. hopefully they'll get caught soon. coming up next, lighter news

you know, after "dancing with the stars" there was a whole hot minute where we didn't see kate gosselin. >> that's up, huh? >> that has completely ended. now she's going to be everywhere. in probably one of the most unexpected announcements we've made on "the skinny," kate gosselin is going to open up the emmys of all things. >> why? >> i think this could actually be a bit interesting. what we're hearing is she's going to be doing a skit with

jimmy fallon. it could be funny, tongue in cheek, it might make sense when we actually see it. she's not nominated for any of the awards. but like i said, it's a funny sketch. where she supposedly interacts with some of tv's biggest stars. the telecast happened august 29th on nbc. you'll see her then. she's also going to be at the very beginning -- rather, tlc is also confirming she will appear on the november 14th episode of sarah palin's "alaska." that show that remember we had heard about all of this, she was going out with the kids to tape it all? >> they were going camping together, something like that. we said it a few weeks ago. >> the funny thing is tlc, the president, had a statement. and you know, kate gosselin, there's been a lot of talk about how she's a bit difficult. part of the statement said, it has become clear that it takes a special individual to thrive in alaska. which i think kind of sums up how that show's going to play out. >> i just don't get why she's a i don't understand.

break it down to me. why do we care? why is she on the emmys? >> i think that the show had a lot of ra cau kids were so adorable, and i think she with jon, they worked, but yeah, i don't know why she is there everywhere still. >> reality tv, man. all right. well, if you're a justin bieber fan you may not like this story. s acs pr foot apparently back in december at a concert in sacramento. i guess someone didn't like the show or whatever but they chucked a water bottle at his head. nails him. front and rhe e size. >> good reflexes. apparently it didn't faze h again, this is back in december inlifoa someone for whatever reason wanted to nail this young guy with a huge water bottle. >> i'm sure it's so different than the normal reception he gets of young girls and old moms going crazy and yelling for him. >> maybe he's -- >> i don't know, that's nasty. >> it could have been a love throw, you know what i mean? some teenage girls.

charges, when he and his fellow convicts, tracy province and daniel renwick, broke out of prison with the help of welch on july 30th. the 35-year-old renwick was arrested the following day in colorado. province was captured monday in meeteetse, wyoming near yellowstone national park. a woman spotted him at a church over the weekend and called police. >> it's extremely scary to me. i think it's way scary. who would ever dream they would show up in meeteetse, wyoming? >> reporter: police say escapees were tied to last week's killing of an elderly couple in new mexico. the fugitives are believed to be white supremacists and fear they are migrating north toward canada. brad wheelis, abc news. a veteran flight attendant is in custody this morning after an argument with a passenger got out of control. police say steven slater cursed the passenger over the plane's p.a. system after that flight arrived here in new york, then he grabbed a beer from the galley and slid down an emergency chute. he was arrested a short time

it is the summer's busiest day of voting with polls open for primary elections in colorado, georgia, minnesota, and connecticut. >> one republican senate candidate in connecticut might be new to politics but as bill weir tells us, she knows a lot about the rough and tumble stuff. >> you're on monday night raw! >> reporter: it is an empire built on smackdowns, heroes and villains, divas and vixens. >> oh my god! >> reporter: and all their choke slams and drop kicks are now worth $1.2 billion in ticket sales, tv rights and merchandising. and there is no confusion over who built this empire because vince and linda mcmahon have always been right in the middle of the action. on any given night the matriarch of the wwe might have caught her husband with his pants down. or caught a slap from her own daughter. or enjoyed a beer and a

beat-down from stone cold steve austin. so for wrestling fans it may be a bit odd to see linda mcmahon like this. >> i'm running for the united states senate. >> i know. >> reporter: from backyard wine tastings to small town coffee klatsches to the county fair, mcmahon now spends every waking hour reinventing herself in every corner of connecticut. and she says she's willing to spend 50 million of her own dollars blanketing airways with ads that are dramatically more civilized than anything she produced before. >> it's time for something different. >> reporter: it's the latest makeover for a woman who married her high school sweetheart and first helped him promote an ill-fated evel knievel stunt. into a global brand. an accomplishment that is the central pillar of her campaign. >> she tamed the traveling show world of professional wrestling, turned it into a global company and created 500 jobs here in connecticut.

>> it's reasonable then to examine how you might govern by examining the wwe throughout the years? >> well, i certainly think you could look at the business side of how wwe was run, which was run as a conservative company and with little debt, maintaining a strong cash balance. >> reporter: there is no debating her financial success. but opponents and critics have plenty to say about how the mcmahons made their fortune. one of their shrewdest moves was to admit that all of this is a show. by branding their wrestlers as performers instead of athletes they avoided costly oversight, state licensing fees, they ducked any obligation to provide their wrestlers health care or pensions after their brutally short careers. >> one medical examiner calculates pro wrestlers die at a rate seven times greater than the general public. why do you think that is?

>> of those performers that were under contract to wwe, five of those premature deaths, one died of an accident, a tragic accident that we had here. then we had, you know, others who have died of natural causes. >> once you testified that it wasn't cost-effective to test for steroids among your employees. do you have any regrets? >> there is a doctor that travels with each group. there are trainers with each group. all of those measures are to create an environment to protect the health and wellness of these individua >> reporter: but beyond the care of her employees, she also faces criticism on the content of their shows. >> oh yeah. oh! >> reporter: the wwe has softened in recent months. no swearing or blood and less female skin now earns them a pg rating. but a group cad mo democrats, points to old clips that would make a nonwrestling fan of any party cringe. the beating of a m

challenged and the repeated degradation and abuse of women. >> we can talk about wwe until tomorrow. but i think the people of our state and what i hear when i'm around in our state is not -- they're not concerned about soap opera story lines. they are concerned about the issues of the day. they're concerned about the debt, the economy of the country, the jobs that they've lost. >> thank you, thank you. >> reporter: mcmahon is a fiscal conservative who opposes president obama on health care and wall street reform, but she is pro-choice and moderate on most other issues, and that is the only way she stands a chance in a deep blue state like this one. but she's hopeful her outsider status will give her the kind of autumn surge scott brown enjoyed in the state next door. given her dignified new friends and image, it's doubtful linda mcmahon would bring this debating style to the halls of

congress. but as one republican delegate put it, she's dealt with testosterone before, she can certainly handle the u.s. senate. >> as someone who grew up watching wwf, now wwe, that's a fascinating story to me. apparently she is way ahead in the polls. she has a pretty good chance of pulling this thing off. >> if we've learned anything from al franken and ronald reagan and the terminator, there's no route to leadership, no set way to get there. >> one can have many careers in this country. coming up next, a japanese inventor shows off a pretty good sense of humor. >> you'll see why his unusual innovations are now gettin

we are the first to admit every now and again we do weird stories. >> no breaking news there. >> yes. this latest one, it's about robots. they're being introduced in japan. a typical robot may walk around,

it may dance, do all types of things. absolutely. the man you're about to meet doesn't do robots but his inventions are pretty amazing. they're aimed at the common man. margaret conley has the story from tokyo. >> reporter: meet kenji, japan's famous inventor of the useful and absurd. his creations range from umbrellas for shoes, to hair splash guards, to chopsticks with fans. his collection is called shindoku, or unusual tool. today he shares with us his subway series. wish list items for those crowded commutes in japan. from a portable hand ring, to a hanging seat. >> it's very useful. >> reporter: kenji demonstrates his portable inventions. >> i'm sure no one will mind this. >> reporter: the sign on his helmet asks commuters to wake him up at his stop. and this is his latest invention for sleepy passengers. here at kenji's labs, the rules are displayed.

among them, his inventions cannot be for real use. >> and a fork. >> reporter: they are not for sale. and they cannot be created for the sole purpose of humor. while some call him an artist, a scientist, or a humorist, his hope is to change perceptions. "i believe that if everybody shares my idea of changing perceptions," he says, "the world could change." one invention at a time. margaret conley, abc news, tokyo, japan. >> i like that thing in the subway. you just relax. that's a good one. >> he's kind of a genius. >> everyday things you think about, he actually makes it into a product, kind of cool. >> i want something for my glasses when i'm walking and

chance of going into puberty as early as 7. >> for folks who are way beyond puberty like us, it's not the prettiest time in your life, so there should be no rush to really get there. >> no. >> no, no. good morning, everybody. i'm rob nelson. >> i'm vinita nair. an intense manhunt continues for a fugitive couple who see themselves as a modern-day bonnie and clyde. >> while they remain on the loose, federal marshals have recaptured one of the arizona prison escapees. don guevara reports. >> reporter: tracy province will be heading back behind bars. after authorities in wyoming caught up with him monday morning. a local resident recognized him outside of a church. >> he immediately denied that he was province. but later admitted that it was him and that he was relieved that this manhunt was over for him.

this video happened on new year's day but it's so interesting we had to show it to you. it just became available. this is a toledo, ohio, woman moments after she was told she couldn't have chicken mcnuggets. >> whoa! >> you can see there she went crazy. melody duchesne attacked a mcdonald's employee after she was told it was too early in the day to order mcnuggets. the 25-year-old even smashed the window using some sort of object, you saw it right there. police tracked her down and she was charged with vandalism. she just wanted nuggets on the first day of the new year, she had to have them. >> when you're hungry, you're

hungry. on a very different note, president obama spent his monday in texas where he raised more than $1.5 million for democrats. >> educaon whe told an audienenclu >> in a sinion, fallen f in gradon >> how dd wee self-satisfied. an othurie y hout-eie hv i think this is a wake-ull. > ra daunce daunce at t 8 n graduates. thing wsure we've got a world >> reporter: some education experts say the problem isn't colleges, but high schools that fail to prepare students once they get there. >> large percentages show up needing some kind of mamati cous to think h ne h >> reporter: to t problem, the president is pusng af would have the same skills. and the president wants to get more students in the door by

making college more affordable, through increased financial aid and student loans. >> it took 30 years to get to number 12. do you think we can really get to number one in 10? >> i do. and is it an ambitious goal? absolutely. is it going to take hard work? absolutely. frankly, failure's not an option here. >> reporter: secretary duncan says everything is on the table. there's talk of adding more school days, hiring an army of new teachers, and of course, raising standards. none of that is cheap, and could be a tough sell for states with tight budgets. yunji de nies, abc news, the white house. >> and the president's goal is that everything will turn around by 2020. so he really is looking ahead. one of the things a lot of people are pointing to, rising costs. it costs a lot to go to college.

>> a ton to go to college. and a root problem in the nation's high schools as well. a lot to fix in the short amount of time he's giving himself so we'll see. the big worldwide threat of frogs. >> why so many of them

welcome back, everybody. scientists are wondering where so many of the world's frogs and toads have gone. now they're trying to do something about it. >> a two-month, four-continent study is getting under way to locate species on the brink of extinction. richard black of the bbc has details. >> reporter: in many parts of the world, the characteristic croaking has been suddenly stilled in recent years. amphibians are in serious trouble, with one-third of species at risk of extinction. >> extinct, extinct, extinct -- >> reporter: many have already apparently disappeared. over the next two months conservationists will mount a series of expeditions to see whether a few individuals may be hanging on. >> we've compiled a list of around 70 species that we know haven't been seen in the last decade. so this is a large, coordinated effort to basically go out and

find or try and find a lot of these species. >> reporter: the most iconic is the golden toad of costa rica. in 1979, it was thriving. a decade later, it had vanished. the biggest threat to amphibians is destruction of the places where they live. but in recent years, a lethal fungal disease has decimated frogs in many parts of the world. there's no way to stop it. the outlook for the world's amphibians is not good but it may look slightly better if the forthcoming expeditions do find any survivors from species missing, presumed extinct. richard black, bbc news. >> the sad reality is that we have some hand in why some of these species are getting extinct. there was a frog called the hula painted frog of israel, last seen in 1955. this is the biggest problem is we were draining all these bodies of water to make sure malaria wasn't brought about, that mosquitos weren't having a chance to linger, there went the frogs. >> trying to do one thing and ended up doing something to the

environment bad.

finally this half hour, here's something we don't talk about often here on "world news." and that is puberty. a new study says more and more girls are reaching it earlier and earlier. >> the reason for that remains unclear. but what is clear are the consequences for young women. here's dr. richard besser. >> reporter: parents are worried about a new study from pediatrics making headlines. >> we're just scared about it because we didn't know if this was something that was going to cause other problems years down the road. >> reporter: chanda lewis' anxiety seems to be supported by

this study which suggests american girls are entering puberty earlier than ever. if true, concerning news. >> girls at earlier onset of puberty are at risk or higher risk for earlier onset of sexual initiation and teenage pregnancy, as well as earlier onset of substance abuse. long-term these girls can be at higher risk for breast cancer and adult obesity. >> reporter: what does this study really say? we asked the senior author. many of the headlines about this study were the age of onset of puberty is going down dramatically. is that a fair conclusion from this study? >> i don't think from this study we can say that the age is going down in the world at large. >> reporter: so despite all the press reports, the girls in the study are not representative of the general population. and some cases were selected because they had existing risk factors for early puberty. >> this study was not actually

designed to look at whether puberty was happening earlier or not. >> reporter: but the trend is going in the wrong direction. with many other studies indicating that girls do face puberty earlier. researchers believe there are two key reasons. increased rates of obesity in children due to poor diet and declining physical activity and chemical and environmental factors. in fact, the authors are actually in the first year of a long-term study, trying to understand whether chemical >> we've done studies to show that heavier girls do have ie o ube but the other issue that's of growing concern is chemicals that are found in everyday household products. >> reporter: critical information for parents hoping to protect their daughters. the ultimate goal of this study is to find preventible risk factors for early puberty. clearly, obesity falls into that category. dr. richard besser, abc news, new york. >> you have to imagine for so many parents out there, this is such an uncomfortable topic of conversation

oprah: we decided to do what we do best and that is a show about and with everyday people. this show always allows people to understand the power they have to change their own lives. if there is one thread running through each show we do, it is the message that you are not alone.
